I am currently running Ubuntu 13.04 on my laptop and I installed compiz-config in order to organize my workspace.
In compiz-config, choosing general options, the last tab is desktop size. Then there are three options, and the last one propose to change the number of desktops. I would like to have two differents desktops but I can't find how to switch between them.
Is there a shortcut to switch between these two (non-virtual) desktops?
